Giving and Taking Stuff from the Player
To give an item to a player (any quantity of it) simply use the following script command:
$player item items/blaa.tik <num>
$player is a targetname that’s automatically recognized as the player. The items/blaa.tik should be replaced by the tik file for the item, relative to the models folder. For example, to give a bratwurst, you’d use items/bratwurst.tik. This command can also be used to give the player weapons, such as weapons/colt45.tik.
To give the player ammo, this script command should be used:
$player ammo type amount
Type is a small string identifier for the type of ammo to give, and amount is the amount of that ammo type to give to the player. The different ammo types are:
? pistol
? rifle
? smg (for sub-machineguns)
? mg (for machineguns)
? grenades
? shotgun
? heavy (for heavy explosive weapons like the bazooka)
To take something away from the player (item, weapon, or ammo) use the following script command:
$player take name
If taking away an item or weapon, name is the tik file of the item or weapon to take. If taking away ammo, name is the string identifier of that ammo type (they’re listed above). This command takes away all of the specified thing, be it items, a weapon, or ammo.
To take away everything the player has, use the following script command:
$player takeall
This takes all items, weapons, and ammo the player has, leaving the poor wretch humiliated and destitute.
